javascript – Como utilizar put e delete em envio de formulário

preciso de ajuda pra usar o delete. Bom, basicamente eu sei que o http só aguenta get e post, mas não sei como resolver, já usei um input hidden com um _method de value DELETE e nada vai, desde já agradeço

HTML:

    <input type="hidden" name="_method" value="DELETE" />

    <div class="input-block ">
        <label for="">Id</label>
        <input class="id" name="id" type="number" required>
        
    </div>
    
    <div class="input-block">
        <input type="submit" value="Deletar">
    </div>
</form>```

Server:
.delete('/delete-product', pages.deleteProduct)

t sql – Reclaiming space after delete statement in SQL Server

I have some tables used in reporting and some of them grow huge with the daily ETL so I have implemented som jobs that delete rows more that x days old. E.g. everyday 10% new data gets added and I delete 10% of the oldest rows in another job.

Do I need to do something for efficiency? Some tables are heaps with nonclustered indexes and some also have clustered indexes. E.g. to I need to rebuild the tables in case of heaps or rebuild index in case of clustered index on the table? If so how often? Most tables are only used once per day and when all joins and calculations are done they get extracted for visualization in a non-live manner.

I know a little about index fragmentation and that one can query fragmentation in percent. How much do I need to worry about the above scenario?

How to Auto -delete rows in mysql database

I am building an online ticketing system where users reserve their ticket before proceeding to the payment activity to make sure that their desired seat is not reserved by someone else while they are trying to validate the payment. A boolean is set to update and set to true upon completion of the payment. However, upon failure, the system might not always get the response and I will like to be able to delete all entries which have not been set to true after existing for 60 seconds. In summary I want a

`DELETE * FROM tickets WHERE reserved_time > 60 seconds AND paid_for = false`  

And I want it to run continiously so that users who can’t pay for their tickets 60 seconds after reservation can release the tickets immediately. I know it’s a long shot but thanks for any attempts .

sharepoint online – How to delete document library with ghost file

I have an empty document library that is unable to be deleted with error “list cannot be deleted while on hold or retention policy” which hints that there are still files inside.

error message

I have even created a new view with no filters but there are no files visible.

empty library

In the Site Contents, the total shows there is 2 documents inside. I also synced the file to my PC and enable “Show hidden files” but still showing empty. I also checked in the library settings at the “Manage files with no checked in version” and yet no files are listed.

Site content showing 2 file count

I also tried to delete the library using PowerShell PnP with -force parameter but it shows the same error message.

Remove-PnPList -Identity $LibraryName -Force -recycle

P.S: If not mistaken the library was migrated from another platform using a migration tool. Not sure if it has anything to do with this

partitioning – Delete 1 EFI partition from the 2 that I have

Situation: Okey, y recently installed Ubuntu on my computer, I wanna have a dual boot machine with Windows and Ubuntu with 2 hard drives, I have a couple of issues with grub which doesn’t show the selection OS menu. So I followed This installation guide there someone recomended than during the installation process create an “EFI/ partition” and select it as “device for boot loader installation”.

I wasn’t aware of what I was actually doing, but that doensn’t solve my problem. I solve it by rebuilding Grub with grub-install.

Here, how the partitions end

Question: Now I realize that what I did was create another UEFI partition (I read that the System just use 1, so I want to delete the one that is remaining safely, so:

  • Wich one delete?
  • How to delete it safely?
